Northeast Light Alloy (Dongqing)
China-company research for source-listed aluminum open-die rings, squares and discs; Harbin, Pingfang District project evidence, with exact order plant and parameters unconfirmed.
Named China company and aluminum open-die products
- Company identity
- The official introduction names 东北轻合金有限责任公司 and its parent, 中国铝业集团高端制造股份有限公司. Northeast Light Alloy (Dongqing) is an editorial English label, not a verified registered English name. The named company is separate from its parent, its New Product Development branch and the Chinalco (Chongqing) sales company mentioned in a news report. Current legal registration has not been independently verified.
- Published product range
- The official forging table, published 5 November 2024, lists aluminum open-die rings, squares and discs. Die forgings appear separately. A freely forged ring is not evidence of ring rolling. Combined alloy, temper and geometry labels are dated catalogue information, not approval of every combination or a quotation for a specific drawing.
- Region and project evidence
- The company-issued 29 July 2026 notice identifies an aluminum forging-line project in Harbin, Pingfang District, Heilongjiang, China. Its street wording is inconsistent between the project and meeting addresses. Only the city and district are recorded here; the specific factory address remains to be checked. The R&D branch contact address is not substituted for the actual order plant, and the shared Beijing footer belongs to the parent group.
- Order boundary
- Confirm the actual contracting and producing entity, responsible forging line, factory address, supplied state and drawing-specific acceptance evidence in the written response. Project-location and catalogue evidence do not establish the factory or permitted parameters for an order.
Separate the freely forged blank from the finished component
For an open-die ring, square or disc blank, define the controlled drawing, units, envelope and supplied state. Agree later machining, material condition and inspection separately. Ring geometry alone does not determine its forming route.
- Blank or finished component
- State the controlled drawing, revision, units and supplied state. Separate the forging drawing from the finished-part drawing, with machining allowances and critical interfaces reviewed by the responsible owner.
- Route, tooling and material state
- Ask for the proposed forging route, alloy and supplied condition. Record included die work, trial parts, heat treatment and subsequent operations where relevant. A generic alloy or process label is not a substitution approval.
- Sample and inspection evidence
- Agree sample identifiers, drawing revision, critical features, material and inspection records, and the person responsible for release. The project reviewer should define any internal-soundness, functional or application-specific acceptance requirements.
- Comparable offer and responsible entities
- Align quantities, included operations, tooling ownership, samples, inspection, packing and destination. Confirm which named company contracts, forges, finishes and dispatches the component. Obtain current commercial terms in the written response.

Official sources, dates and manual research route
Sources reviewed . The product table is dated 5 November 2024, the production-line report 29 October 2025, and the project notice 29 July 2026. These publication dates differ from the review date.

- Company introduction and parent identityhttps://dq.chinalco.com.cn/gywm_394/ghhd/
- Company contact page; image gives company name and telephonehttps://dq.chinalco.com.cn/fwzx/lxwm/
- Dated forging-line report; sales collaborator kept separatehttps://dq.chinalco.com.cn/xwzx_399/gsyw/202510/t20251029_157297.html
- New Product Development branch contact, not an order-plant identificationhttps://dq.chinalco.com.cn/kyykf_101/yfjg/
- Harbin/Pingfang forging-line project notice; inconsistent street wordinghttps://dq.chinalco.com.cn/zbgg_101/ywgg/202607/t20260729_174532.html
The project notice does not confirm a current order plant, completed inspection or a released part. The published figures and application topics are not universal capacity, qualification or commercial promises. Review the official company route before manually sharing requirements; no company has been contacted.
Record status and evidence limits
Current certificates, capacity, stock, minimum orders, prices and lead times remain unconfirmed. No supplier approval or paid placement is established. Published forming routes and application topics do not release a component for a project.
Continue the open-die source research
The tracker starts with Not contacted. These are source-research choices, not interchangeable products or approved factories. Tools keep local drafts and downloads for manual review; selecting a company does not send a message.
Additional aluminium profile, plate and strip catalogue evidence
- Aluminium extruded profiles — The aluminium profile row lists 2, 3, 5, 6 and 7 series alloys, typical temper options and a circumscribed diameter range. Magnesium entries on the same source page are outside this record.
- 6061-T651 aluminium plate — The manufacturer plate table lists a 6061 row with T651 and F options. This record selects the listed T651 option for catalog research; it is not a stock item or a current offer.
- 1050 aluminium strip — The strip catalogue includes a 1050 row with O, H14 and H18 options and dimensional ranges. The source groups sheet, strip and foil; coil condition, exact cut form and chosen combination need confirmation.
These are three added product records under the existing Dongqing company. They do not represent three additional companies. Its existing open-die forging evidence and primary directory route remain available.
Catalogue date, identity and manufacturing-region boundary
The introduction names 东北轻合金有限责任公司 and reports affiliation with 中国铝业集团高端制造股份有限公司. The shared group footer uses a Beijing address; it is not used here as a Dongqing factory address. A 29 July 2026 forging-project notice places that project in Harbin, Pingfang District and uses inconsistent street wording. This supports dated regional manufacturing context, not a verified street address or the plant assigned to these profile and rolled-product orders.
Company introduction and reported parenthttps://dq.chinalco.com.cn/gywm_394/ghhd/ · Dated Harbin/Pingfang project noticehttps://dq.chinalco.com.cn/zbgg_101/ywgg/202607/t20260729_174532.html
The catalogues were published 5 November 2024 and their actual bodies were read 8 October 2026. Listed ranges are dated supplier catalogue information, not current inventory, a quotation or a verified combination for an order. Confirm the chosen alloy and temper, drawing, dimensions, tolerances, finish, inspection, MOQ, price, lead time, contracting company and assigned production plant in writing.
